🌦️ main predictors of presence were meteorological factors (temp, atmo pressure, rainfall) 🌱 low (<3m) vegetation drives abundances, 🌳 more mosquitoes in urban parks and residential (with gardens) areas than in densely built areas. #rstats #randomforest #openscience

🦟 We model the impact of attractive, inert, and deterrent ITNs (insecticide-treated nets) on malaria transmission. Data & model: buff.ly/MD5xO99 Key result 👉 Attractive ITNs may reduce malaria transmission more effectively than deterrent ones, even under physiological or behavioral resistance.

🚨 New publication! Our RCT in 🇧🇫 Burkina Faso & 🇨🇮 Côte d’Ivoire shows that adding either non-pyrethroid indoor residual spraying (IRS) or intensive behaviour change communication (BCC) to LLINs reduces #malaria burden. In @lancetgh.bsky.social : doi.org/10.1016/S221... #GlobalHealth #VectorControl

🦟 The Anopheles gambiae Complex is more than a group of sibling species—it’s a key player in malaria transmission across Africa. With diverse ecologies and behaviors, its members adapt to unique habitats, making them formidable vectors of malaria parasites. 🌍 (4/4) #Malaria #VectorBiology

🙏 Let’s honor the legacy of the researchers and techs behind this milestone and the transformative impact of pyrethroids-treated nets on #globalhealth. I had the chance to meet F. Darriet and V. Robert, that were also prolific writers 📚 ⬇️, before their quiet retirement from @ird-fr.bsky.social .

🔬 The 1983 study was the first field trial to show the impressive efficacy of permethrin-treated nets against malaria vectors, even when perforated. These findings (published in 1984) were pivotal in establishing insecticide-treated nets (ITNs) as a cornerstone of malaria prevention​...

🕰️ Insecticide-treated mosquito nets were sporadically tested from the 1930s, with limited success, until the late 1970s, when Hamon and Quélennec at WHO provided critical impetus for research into safer and more effective pyrethroids, setting the stage for Darriet et al.'s works...

⏰ Every morning at dawn (even weekends!), this beauty comes to tap on the window: Halcyon malimbica, the blue-breasted tree kingfisher (🇫🇷 Martin-chasseur à poitrine bleue). Unlike their English name suggests, Halcyoninae are not specialist fishers. 📍Casamance, #Senegal 🇸🇳. #Birds

(2/2) 🇫🇷 In the official French translation by Edmond Barbier (1875), this passage takes on a bit more alarming tone ⚠️ 😅. Back to English: "A mere glance cast upon what the complete catalog of the future will be would be enough to forever shatter an entomologist’s rest." #Entomology #Darwin 🧪

📜 Darwin’s wisdom for tropical entomologists 🦟 🦋 (1/2). In: "The Voyage of the Beagle" (1839), Chapter II: Rio de Janeiro: "It is sufficient to disturb the composure of an entomologist's mind, to look forward to the future dimensions of a complete catalogue." 🧵 #Entomology #Darwin 🧪

Reproduction of frontispiece by Robert Taylor Pritchett from the first Murray illustrated edition, 1890: HMS Beagle in the Straits of Magellan at Monte Sarmiento in Chile.The cabinets of Europe can, as yet, boast only of the larger species from tropical climates... sufficient to disturb the composure of an entomologist’s mind, to look forward to the future dimensions of a complete catalogue.

The (good!) reason why he published here: www.nature.com/articles/151...
WHEN eastern Europe has been devastated and its indigenous culture suppressed, it is particularly gratifying to find a band of refugee professors and lecturers combining to keep the stream of their learning from drying up. Polish Science and Learning (No. 2, February 1943, Oxford University Press) is the second of a series of booklets prepared by Polish scholars in Great Britain in collaboration with their British colleagues. An article by Charles Elton on “ The Changing Realms of Animal Life” is contributed as “something new towards maintaining the concept of international co-operation in science after the war is over”,
